Please consider the following snippet.
```
\input texinfo
@documentlanguage en
@documentencoding UTF-8
foo
@cindex (
@cindex [
@cindex A
@cindex Z
bar
@printindex cp
@bye
```
Processing with `texi2any --pdf` version 7.1 yields the index entry
order '([AZ', which is what I want. However, using the version from
git, I get '(AZ[' instead.
What must I do to get the old collation scheme back, i.e., all special
characters come before the alphabetical ones?
